Abstract

Provided are a reference signal detection method, a receiving method, a user equipment and a base station. The user equipment comprises: a determination unit used for determining configuration information about a reference signal, the configuration information comprising information about a first candidate time-frequency resource and a second candidate time-frequency resource, wherein the first candidate time-frequency resource comprises a first partial time-frequency resource and a second partial time-frequency resource, the first partial time-frequency resource being a first partial resource in a first silent time-frequency resource, and the second partial time-frequency resource being a second partial resource in a second silent time-frequency resource; and the second candidate time-frequency resource comprises a third partial time-frequency resource and a fourth partial time-frequency resource, the third partial time-frequency resource being a third partial resource in the first silent time-frequency resource, and the fourth partial time-frequency resource being a fourth partial resource in the second silent time-frequency resource, wherein the first partial resource, the second partial resource, the third partial resource and the fourth partial resource are not overlapped with one another; and a detection unit used for detecting the reference signal according to the configuration information. The embodiments of the present invention can increase the cell discovery and measurement performance.
